FOULING PLUGS

I have a 2001 426f and the plugs seem to be constantly fouling. Does any one have any ideas on how fix the problem.

Changing brands of gasoline completely solved my plug fouling with my '01. I was using Mobil which fouled plugs. Chevron and Sunoco works OK for me now. Other people have had other solutions but I hope this one works for you (it's the easiest). :)

The first thing that comes to mind is you are experiencing a rich condition. When are you fouling plugs, when you are starting the bike and it is cold or when the bike is warm? You might need to go a step leaner on your jetting because as the temparature warms up, it will create a rich condition and the opposite is true when the weather starts cooling off again. The reason being, hot air is less dense than cold air. :)
